Online Dissolved Oxygen Meter

An Online Dissolved Oxygen (DO) Meter is an analytical instrument used to continuously measure the amount of gaseous oxygen dissolved in a liquid in real-time. Core Features Continuous Monitoring: Provides non-stop, real-time data tracking directly from the process line or aeration tank, eliminating the delay of laboratory grab testing. Advanced Sensing Options: Utilizes either optical luminescent sensors (highly stable with low maintenance) or galvanic/polarographic electrochemical sensors to detect oxygen molecules. Process Automation: Outputs signals (like 4-20mA or Modbus) to control systems to automatically regulate equipment like aeration blowers, saving energy while maintaining target oxygen levels. Typical Applications Wastewater Treatment: Controls aeration basins to keep bacteria alive and breaking down waste efficiently. Aquaculture: Monitors commercial fish and shrimp ponds to prevent sudden oxygen depletion and mass mortality. Industrial Processing: Protects power plant boilers from corrosion by verifying that oxygen has been stripped from the feed water.
